Israir have a mixture of A320 & B757 which might be seen at LTN, another STN loss.
As for Harpenden, bring back the Court Line fleet, grew up with them above and had no issues, in fact we had 2 pilots and a couple of ground crew living in our road. Things just gone silly in AL5 postcode, mostly commuters anyhow other than the retired bank managers, have you ever seen so many estate agents in a single high street!
